Linlithgow MP Martyn Day has called for a pledge to hold a second referendum on Scottish independence to be included in the SNP manifesto for next year’s Holyrood elections.
The SNP member said the option of a second vote “needs to be kept open”.
Both First Minister Nicola Sturgeon and her predecessor Alex Salmond have previously suggested last year’s referendum, which produced a majority no result, was a “once in a generation” event.
There has been increased speculation in recent weeks that the SNP will include a promise to hold a second vote at a future date in their manifesto for the Scottish Parliament election in May, prompting Prime Minister David Cameron to say he would not authorise another referendum while he remained in power.
Speaking to the Independence Live website, Mr Day said: “I think there will be another referendum, I’m just not sure when. I think it needs to be kept open in the manifesto.
“I wouldn’t want to rush into another referendum, it has to be when the Scottish people are ready.”
He continued: “We know the faultlines we failed on in the last one. We didn’t win enough of the elderly pensionsers, particularly older women, we didn’t convince enough people of the currency arguments or the business scares. We know that’s what we have to address.
“Once we address that, possibly combine it with a divisive EU referendum that could see Scotland and England voting differently, we might have the grounds for a snap referendum.”
